Explore Java generics in this detailed example focusing on creating flexible, type-safe code with generic classes, methods, and interfaces. In this tutorial, we define a PairContainer class with multiple type parameters (K, V), demonstrate the use of bounded type parameters to restrict data types, and utilize wildcards for broader compatibility with unknown types. Learn how Java generics enhance code reusability and adaptability by defining flexible key-value pairs, using wildcards, and applying bounds to ensure numeric values. Perfect for Java beginners and developers aiming to master type safety and efficient data handling with generics.
